Hi Raj I was just as strong on both sides up until about ten tears ago. and my right side gradually got weaker. Then about three years ago the tremors began in my right foot and has been gradually getting worse since then. I was Diagnosed with PD about a year ago at the age of 45. To be honest I do not know what ET is, my doctors never mentioned it. I wish you the best, Keith ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
